At this time, the medical staff need to hold the armrest 14 with the left hand and the handle 5 with the right hand. After the preparation action is completed, aim the needle 2 at the blood vessel of the livestock and insert it to start vaccination. It can be operated more easily and reduce the physical burden required by the operator during the injection process, especially in the case of a large number of vaccinations. At the same time, during the vaccination process, the stability of the device during the injection process can be ensured, which helps to improve the accuracy and effect of vaccination, and can also protect the health of livestock and reduce the operation risk. The cross-shaped push plate 9 contacts the syringe 1, the syringe 1 contacts the semi-cylindrical sleeve 4, and the connecting column 10 is slidably connected to the inner wall of the syringe 1. At the same time, before the device is used, a part of the syringe 1 is pulled out of the inside of the semi-cylindrical sleeve 4. When the syringe 1 cannot be pulled out further, at this time, the medical staff connect the medicine bottle to the needle 2. At this time, the electric telescopic rod 6 will start. The telescopic end of the electric telescopic rod 6 drives the cross-shaped push plate 9 to move. The movement of the cross-shaped push plate 9 will drive the sealing circular plate 11 to move. During the movement of the sealing circular plate 11, the medicine can be drawn from the medicine bottle into the inside of the syringe 1 through the needle 2. After the medicine extraction is completed, the electric telescopic rod 6 will drive the cross-shaped push plate 9 to move. The cross-shaped push plate 9 will drive the sealing circular plate 11 to move. The sealing circular plate 11 will drive the syringe 1 to move. The movement of the syringe 1 drives the needle 2 to move. The needle 2 will insert into the blood vessel of the livestock during the movement. At the same time, the syringe 1 will contact the limiting block 12. At this time, the syringe 1 cannot continue to be inserted forward. The electric telescopic rod 6 will continue to push the cross-shaped push plate 9 to move. The cross-shaped push plate 9 will push the connecting column 10 to move.

[0016] The fixing mechanism 7 includes a second connecting block 701, a suction column 702, a connecting rod 703, a first elastic telescopic rod 704, and a water-absorbing sponge 705. The second connecting block 701 is fixedly connected to the circumferential surface of the semi-cylindrical sleeve 4. The suction column 702 is fixedly connected to the inner wall of the second connecting block 701. The connecting rod 703 is fixedly connected to the circumferential surface of the suction column 702. The first elastic telescopic rod 704 is fixedly connected to the left side of the connecting rod 703. The water-absorbing sponge 705 is fixedly connected to the telescopic end of the first elastic telescopic rod 704. The fixing mechanism 7 further includes a sliding column 706, a sealing block 707, a rubber ring 708, and a connecting plate 709. The sliding column 706 is slidably connected to the inner wall of the suction column 702. The sealing block 707 is fixedly connected to the circumferential surface of the sliding column 706. The rubber ring 708 is fixedly connected to the circumferential surface of the suction column 702. The connecting plate 709 is fixedly connected to the circumferential surface of the sliding column 706. The sealing block 707 contacts the suction column 702, and the connecting plate 709 contacts the cross-shaped push plate 9. Before the device is used, the hair in the area where livestock needs to be injected is removed. Then, the medical staff aligns the rubber ring 708 and contacts it with the skin of the livestock. At this time, the movement of the cross-shaped push plate 9 can drive the movement of the connecting plate 709, and the movement of the connecting plate 709 can drive the movement of the sliding column 706. When the sliding column 706 moves, it will drive the sealing block 707 to move. The movement of the sealing block 707 can extract the air inside the suction column 702, making the inside of the suction column 702 in a vacuum state. At this time, the rubber ring 708 can adsorb on the skin surface of the livestock, which can improve the fixing stability of the device, help reduce the inaccuracy of the inoculation position or the instability of the needle 2 caused by the sudden movement or struggle of the livestock, thereby ensuring the accuracy and safety of the injection. At the same time, during the process of the medical staff aligning the rubber ring 708 with the skin of the livestock, the water-absorbing sponge 705 will contact the skin surface of the livestock earlier than the rubber ring 708. During the process of the medical staff pushing the rubber ring 708 to contact the skin of the livestock, the water-absorbing sponge 705 will be squeezed, and the water in the water-absorbing sponge 705 will flow on the skin surface of the livestock. A small amount of water on the skin surface can form a lubricating layer between the suction cup and the skin, reduce the interference of air, enable the suction cup to better contact the skin, increase the adsorption force, avoid wrinkles on the skin caused by dryness or tension, and ensure closer contact between the suction cup and the skin.

[0017] Working principle: Before the device is ready to be used, medical staff install the syringe 1 in the groove of the semi-cylindrical sleeve 4. At this time, the medical staff need to hold the armrest 14 with the left hand and the handle 5 with the right hand. After the preparatory action is completed, aim the needle 2 at the blood vessel of the livestock and insert it to start inoculation. It can be operated more easily and reduce the physical burden on the operator during the injection process, especially in the case of a large number of inoculations. At the same time, during the inoculation process, the stability of the device during injection can be ensured, which helps to improve the accuracy and effect of inoculation, and can also protect the health of livestock and reduce the operation risk. At the same time, before the device is used, a part of the syringe 1 is pulled out of the inside of the semi-cylindrical sleeve 4. When the syringe 1 cannot be pulled out further, at this time, the medical staff connect the medicine bottle to the needle 2. At this time, the electric telescopic rod 6 will be activated. The telescopic end of the electric telescopic rod 6 drives the cross push plate 9 to move. The movement of the cross push plate 9 drives the sealing circular plate 11 to move. During the movement of the sealing circular plate 11, the medicine can be drawn from the medicine bottle into the inside of the syringe 1 through the needle 2. After the medicine extraction is completed, the electric telescopic rod 6 drives the cross push plate 9 to move. The cross push plate 9 drives the sealing circular plate 11 to move. The sealing circular plate 11 drives the syringe 1 to move. The movement of the syringe 1 drives the needle 2 to move. The needle 2 will insert into the blood vessel of the livestock during the movement. At the same time, the syringe 1 will contact the limit block 12. At this time, the syringe 1 cannot continue to be inserted forward. The electric telescopic rod 6 will continue to push the cross push plate 9 to move. The cross push plate 9 will push the connecting column 10 to move. The connecting column 10 will push the sealing circular plate 11 to move. At this time, the sealing circular plate 11 will move inside the syringe 1. During the movement of the sealing circular plate 11, the medicine inside the syringe 1 can be squeezed and injected into the blood vessel of the livestock through the needle 2, which can improve the efficiency of livestock inoculation, quickly and accurately complete each injection, and reduce the manual operation time of the operator.

[0018] Before using the device, the hair in the area where the livestock needs to be injected is shaved off. Subsequently, the medical staff aligns the rubber ring 708 and makes it contact with the skin of the livestock. At this time, the movement of the cross-shaped push plate 9 can drive the movement of the connecting plate 709, and the movement of the connecting plate 709 can drive the movement of the sliding column 706. When the sliding column 706 moves, the sliding column 706 will drive the movement of the sealing block 707, and the movement of the sealing block 707 can extract the air inside the suction column 702, making the inside of the suction column 702 in a vacuum state. At this time, the rubber ring 708 can be adsorbed on the skin surface of the livestock, which can improve the fixing stability of the device, help reduce the inaccuracy of the inoculation position or the instability of the needle 2 caused by the sudden movement or struggle of the livestock, thereby ensuring the accuracy and safety of the injection. At the same time, during the process of the medical staff aligning the rubber ring 708 with the skin of the livestock, the water-absorbing sponge 705 will contact the skin surface of the livestock earlier than the rubber ring 708. During the process of the medical staff pushing the rubber ring 708 to contact the skin of the livestock, the water-absorbing sponge 705 will be squeezed, and the water in the water-absorbing sponge 705 will flow on the skin surface of the livestock. A small amount of water on the skin surface can form a lubricating layer between the suction cup and the skin, reduce the interference of air, enable the suction cup to better contact the skin, increase the adsorption force, avoid wrinkles on the skin due to dryness or tension, and ensure closer contact between the suction cup and the skin.

[0019] Please refer to Figures 1-7, on the basis of the above embodiments, in another embodiment of the present invention, the pushing mechanism 8 includes a long column 801, a marked circular plate 802, a second elastic telescopic rod 803, and a fixing plate 804. The second elastic telescopic rod 803 is fixedly connected to the inner wall of the first connecting block 13, and the fixing plate 804 is fixedly connected to the telescopic end of the second elastic telescopic rod 803. The long column 801 is fixedly connected to the inner wall of the fixing plate 804, and the marked circular plate 802 is fixedly connected to the circumferential surface of the long column 801. When the device is in use, after the vaccination of livestock is completed, the operator can push the long column 801. The movement of the long column 801 will drive the movement of the marked circular plate 802. When the marked circular plate 802 moves, the marked circular plate 802 will contact the skin of the livestock, and the marked circular plate 802 will make a mark on the skin surface of the livestock. Making a mark can avoid repeated vaccination of the same livestock. Especially when multiple vaccinations are carried out, it can ensure that each animal is vaccinated with different vaccines at the predetermined time and position, and avoid repeated injection of the same vaccine, which affects the immune effect. The pushing mechanism 8 further includes a connecting circular block 805, an L-shaped plate 806, a connecting long rod 807, a second connecting column 808, an L-shaped block 809, a third connecting column 810, and a semi-circular block 811.

The long column 801 contacts the first connecting block 13, the long column 801 contacts the handle 5, the L-shaped block 809 is slidably connected to the inner wall of the handle 5, and the semi-circular block 811 contacts the long column 801. At the same time, during the movement of the sliding column 706, the sliding column 706 will drive the movement of the connecting circular block 805, the movement of the connecting circular block 805 will drive the movement of the L-shaped plate 806, the L-shaped plate 806 will drive the movement of the connecting long rod 807, the movement of the connecting long rod 807 will drive the movement of the second connecting column 808, the movement of the second connecting column 808 will drive the movement of the L-shaped block 809. At this time, the L-shaped block 809 will move downward, the L-shaped block 809 will drive the third connecting column 810 to move downward, the third connecting column 810 will drive the semi-circular block 811 to move downward. After the semi-circular block 811 moves downward for a certain distance, the semi-circular block 811 no longer wraps and clamps the long column 801. At this time, the long column 801 can move, avoiding that during the use of the device, the operator accidentally touches the long column 801, resulting in the marked circular plate 802 marking the unvaccinated livestock, which affects the health and safety of the livestock.

[0020] Working principle: When the device is used, after the vaccination of livestock is completed, the operator can push the long column 801, and the movement of the long column 801 will drive the marking circular plate 802 to move. When the marking circular plate 802 moves, the marking circular plate 802 will contact the skin of the livestock, and the marking circular plate 802 will make a mark on the skin surface of the livestock. The marking can avoid repeated vaccination of the same livestock, especially when multiple vaccinations are carried out, it can ensure that each animal is vaccinated with different vaccines at the predetermined time and site, avoiding repeated injection of the same vaccine and affecting the immune effect. At the same time, during the movement of the sliding column 706, the sliding column 706 will drive the connecting round block 805 to move, and the connecting round block 805 will move. The movement of the round block 805 will drive the L plate 806 to move, the L plate 806 will drive the connecting long rod 807 to move, the movement of the connecting long rod 807 will drive the connecting column two 808 to move, the movement of the connecting column two 808 will drive the L block 809 to move, at this time the L block 809 will move down, the L block 809 will drive the connecting column three 810 to move down, the connecting column three 810 will drive the semi-arc block 811 to move down, after the semi-arc block 811 moves down a distance, the semi-arc block 811 no longer wraps and clamps the long column 801, at this time the long column 801 can move, to prevent the operator from accidentally touching the long column 801 during the use of the device, causing the marking circular plate 802 to mark the unvaccinated livestock, affecting the health and safety of the livestock.
